Full of Air or Full of Water?

We planned simple games to play with the kids at the children's home that didn't require special toys or equipment, games that helped teach English or where just fun for everyone.

And then we pulled out the balloons. A group of girls I was playing with asked for a few balloons and then disappeared. I guessed they had run off to start another game. But then they returned, their balloons full of water! We had fun tossing the water balloons back and forth until they popped, cooling us off from the mid-day heat.
